Problem 3.118

A metal ball weighing 0.2 lb is dropped from rest in a fluid. It is observed that after falling 1 ft, the ball has a speed of 2.25 ft/s. If the magnitude of the resistance due to the fluid is given by Cdυ,where Cd is a drag coefficient and υ is the ball’s speed, determine the value of Cd.
